Now I first attempted this with one of those PORTABLE POCKET WI-FI devices, in fact I'm using one right now since I don't own a bulky paid monthly Wi-fi.

It wasn't working on my Samsung S5. At first I thought it was a device problem(maybe the pocket wi-fi isn't powerful enough), so I went ahead and connected the device to my PC Via USB CABLE and it still wasn't working.

I tried separate browsers on my phone, the default browser displayed a simple "Webpage not available" text and the Chrome displayed a blank white screen.
